HAOMEI Aluminum specializes in manufacturing ROPP caps, aluminum-plastic composite caps​, and tamper-evident screw closures—ideal for packaging olive oil, alcoholic beverages, and cosmetics. We also offer full support for anodizing surface treatment proce
HAOMEI Aluminum produces bottle caps with a diameter of 30x24mm and 31.5x24mm. The bottle caps are equipped with a broken bridge anti-theft ring. The ring breaks when the user opens it, ensuring visibility when opening it for the first time.
The olive oil bottle is sealed with a ROPP aluminum bottle cap + plastic inner cap, and the outside is sealed with a plastic film, which has a certain anti-theft effect.
The 31.5mm aluminum-plastic cover has a standard spiral design, a built-in anti-backflow structure, and is made of a composite material of aluminum and plastic, taking into account both sealing and anti-counterfeiting properties.
HAOMEI provide various sizes of ROPP caps / plastic caps / screw caps / metal caps, with 31.5x24 mm caps​ being the most commonly used. Customization is available upon request.
The olive oil aluminum bottle cap achieves physical anti-counterfeiting through a ratchet anti-theft ring + twist-off bridge, and is equipped with a food-grade sealing gasket to ensure the freshness of the oil.
